“The deployment of 2 tonnes within the Essilor International teams contributes to awareness , mobilization and real empowerment of employees. The approach positive, participatory, solution-oriented workshop allows everyone to understand their carbon footprint and concrete ways to reduce it to contribute to the goal of carbon neutrality by 2050. The workshop  also helped to generate an exponential internal dynamic, arousing the enthusiasm of new participants and departments, creating links between international teams and receiving the good report of the management teams. This dynamic is also supported by a growing number of leaders and by the constitution of an internal community , which activates exchanges, debates, and learning on the climate , of which a growing proportion of employees are concerned. These leaders are gradually becoming enlightened ambassadors of the climate issue , internally and externally, as well as catalysts for initiatives, thus helping to make Essilor a learning and active organization .
